sor at a pressure exceeding that of a mixture of the motor fiuid and the gaseous fluid to b compressed.

Another object is to provide a rotary com'- pressor in which the energy necessary for rotation is derived from the reaction of a motor iuid on the walls of a plurality of special- 1 ly positioned rotatable tuyres.

Further objects will appear in the course of the detailed description now to be given with reference to the accompanying drawings, in which Fig. 1 is a section taken at" right angles to the axis of rotation of one illustrative embodiment ofthe invention;

Fig. 2 represents a longitudinal section of the same apparatus;

Figs. 3 and 4 are a pair of sections similar to Figs. l and 2 showing a second form of the invention;

Fig. 5 is an axial section vthrough a third constructive embodiment of the invention.

Referring to Figs. l and 2, there is shown a passage for a gaseous motor iiuld A extendf ing through the rotor shaft,-a hollow rotor B, having a plurality of non-radial tuyres C formed therein,-a plurality of ribs or blades F formed on the exterior of rotor B,-a diffuser G provided with non-radial ypartitions IPL-a volute I terminating in discharge con; duit K,-and abilateral inlet Efor a gaseous fluid to be compressed.

The hereinabove described assembly functions as follows The motor fluid entering through A passes through tuyres C and reacts on tlienon-radial Walls of the latter' to cause rotation of rotor B in the direction of arrow D (Fig. l) as the fluid being discharged intothe latter by bladesF; the combined iiuids enter the neck of element G, traverse the passages formed by partitions H, .which function to counteract possibley losses due tolocalv eddy currents, and discharge through volute I intoconduit4 K. It isobvious that; the use of `partitions Hland of bladesF vis )optionah the apparatus being operative, though less efficient, when they; areeliminated. It is further to be observed tha'tthe motor fluid and the iuidto be compressedv may be similar.v or' dissimilar,`

and differs from the one already described only inthe manner in which rotor B is set-in motion.' 1 Here, tuyres Lare radial, and the energy Vnecessary for actuating element B is derived froma pulley M, a direct connect edrnotor orthe like. This structure func-v tions substantially in the same mannera's the one represented -infFigs l and 2, the fluid discharging vthrough tuy`eres. L serving merelyV to increase the velocity of those aspi-Y rated from feed conduits E.

j In the modificationillustrated` in Fig. 5,

motor fluidv under pressure is fed through conduit N and discharges in a` direction substantia'lly' parallel to the axis ofjrotation ofl the rotor through. tuyres O intoafflarindiffuser R; fluid to be compressed or ejected being Vaspirated through feed conduit Pfby means of propeller blades Q.. 4Theirotor may be rotated by either inclining tuyres O or by adding a pulley in the manner suggested by Figs. l and 4L.

Theinvention is particularly adapted for use in evaporating, concentrating or distilling apparatus in which steam under low pressure is to be compressed and used for heating.

What I claim is Vl. In combination, a rotor having a passage formed therethrough, a conduit positioned to provide gaseous fluid under pressure to said passage for turning said rotor, a conduit positioned to feed gaseous fluid exteriorly tosaid rotor, and a fluid discharge system of continuously increasing. section positioned to receive the combined discharge of fluid Cit) from the-passage through the rotor and that vfed to the exterior of the latter, said fluid discharge system being positioned adjacent the periphery of the rotor and in line With the discharge end of the passage in the rotor.

In combination, a rotor having a passage formed:therethrough,.a conduit posi-1 tioned-,toie'edlgaseous fluid under pressure to said passage, a chamber positioned eX- teriorly with relation to said rotor and positioned to feed gaseousffluidltowthte rotor-pw plurality of blades rigidly attached to said rotor and adapted to exert an impelliiig-ef-'f feet on fluid contaiiiediii said chamber, .and
